1 Claim. 1

This invention relates to a clamp which is adapted to be used with asupport for peanut vending machines.

In the past, all types of clamps in use with supports for peanut vendingmachines have had a tendency to break or become useless through wear,and accordingly, therefore, it is an object of this invention to providea clamp that is durable, simple in construction and operation, and Willoutlast the types of clamps in use in the past.

With the above and other objects and advantages in view, the inventionconsists of the novel details of construction, arrangement andcombination of parts more-fully hereinafter described, claimed andillustrated in the accompanying drawing in which:

Figure l is an elevational view partly in section of an embodiment ofthe invention;

Figure 2 is an edge view thereof;

Figure 3 is a bottom plan view thereof;

Figure 4 is a sectional view of the top clamping member;

Figure 5 is a sectional view of the bottom clamping member and Figure 6is a top plan view in reduced scale, showing the various positions inwhich the support can be placed.

Referring more in detail to the drawing, the reference numeral I0designates a rod-like supporting arm having an upper straight portionand a lower straight portion l2, which are joined by an inclined portionl3. The portion II is threaded at M to receive the cup-shaped supportingdisc l5, and a nut i6, when tightened, will lock the disc thereon. Theportion I2 is threaded at I l to receive the threaded bore |8 of theupper clamping member l9, which is then positioned on the upper surfacelot a suitable support 20.

The lower clamping member 2| is then loosely mounted on the portion I2by means of the smooth bore 22, which in this position is in alinementwith the bore i8 of the member I9. A nut 23 is then threaded onto thethreaded portion ll of the portion |2 until the member 2| engages theundersurfaee of the support 20. To firmly clamp the members l9 and 2| onthe support 20, a screw 24, having a knurled end 25, is threaded intothe threaded bore 28 of the member 2|, and moved upwardly until itengages the seat 21 in the member I8, whereupon further upward movementwill expand the rear ends of the members l9 and 2| to firmly retain themembers on the support 20.

Before the nut 23 is firmly threaded onto the portion l2, the arm may bepositioned in any of the positions shown in Figure 6.

There has thus been provided a clamping means for a support which issimple in construction and operation, and it is believed that thestructure and operation thereof will be apparent to those skilled in theart.

It is also to be understood that changes in the minor details ofconstruction, arrangement and combination of parts may be resorted to,provided they fall within the spirit of the invention and the scope ofthe appended claim.

Having thus described the invention, what is claimed as new and desiredto be secured b Letters Patent is:

A device of the character described, comprising a supporting arm havingthreaded lower and upper ends, upper and lower straight portions, and aninclined portion joining said upper and lower portions to form a unitstructure an upper clamp member having a threaded bore for threadablymounting said upper clamp member on the lower end of said arm, a lowerclamp member with a smooth bore for loosely mounting said lower clampmember on said arm, means threadably mounted on said arm below saidlower clamp member to force said clamp members together, a threaded borein the lower clamp member spaced from the smooth base therein, a seat inthe upper clamp member spaced from the threaded bore therein, and meansthreadably mounted in the threaded bore in said lower clamp member andloosely received in the seat in said upper clamp member to expand therear ends of said clamp members to firmly retain said clamp members on asupport.
